[Feature] Count only *.tar files in backup routine (rclone)

[Heart1010]

Describe the feature or change in detail

I added rclone before 1.7x release so I already did sync my /backup folder to pcloud in my case (with rclone).
So every file inside /backup was uploaded to the cloud.

Now with v1.7 and officially rlcone support the auto backup to pcloud didn't work.
It turned out the reason was I had also all *.log files in my pcload folder and because of that the v-backup-user script has counted these log files also (and not just the *.tar files) which ended in uploading the the backup file to pcloud and immediately deletion of not just the old *.tar file but all two *.tar files.

So Jaap and I discussed if it's not a good idea to only count *.tar files (see if [ "$backups_count" -ge "$BACKUPS" ]; ....)

Would you like to sponsor this feature to have it implemented?

No
